BaseTools: Retrieve git version info

[edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Pankaj Bansal 4 years, 3 months ago

Retrieve git version info and save as environment variable
These variables can be used in modules to print the vesrion
info when uefi boots.
This helps in identifying the codebase from logs.

Notes:
    When i ran PatchCheck.py script on this patch i received two errors:
    1. Line ending ('\n') is not CRLF
    2. The commit message format is not valid:
     * Contributed-under! (Note: this must be removed by the code contributor!)
    
    I have fixed the [2] but i have not fixed [1], as this file's line endings
    are already unix like. Please suggest if i need to change these to windows
    like?

Re: [edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Bob Feng 4 years, 3 months ago

Hi Pankaj,

I would have some questions.  Which module or tool will read WORKSPACE_GIT_VERSION and PACKAGES_PATH_GIT_VERSION?
PACKAGES_PATH can include multiple path separated by ";",  looks this patch can't handle such case.
Why is this function implemented in build wrapper?

Thanks,
Bob

Why is this function implemented in build wrapper?

     Or if a UEFI driver/application has been loaded in system from shell, which was the commit version for that?

Re: [edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Bob Feng 4 years, 3 months ago

Hi Pankaj,

I think if the firmware module need to show git version information, the version information need to build into firmware binary but not set to OS environment variable.

Thanks
Bob

Re: [edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Pankaj Bansal 4 years, 3 months ago

Hi Bob,

This OS environment variable is only defined up until the point build command is running.
As soon as build command finishes, these OS environment variables also vanish.

Regards,
Pankaj Bansal

Re: [edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Bob Feng 4 years, 3 months ago

Hi Pankaj,

With your example in previous mail, I understand the usage model. Thanks.
What about adding a scripts in BaseTools/Scripts to implementing this function? I'd expect the build wrapper only have the simple logic of calling build.py.

Thanks,
Bob

Hi Bob,

This OS environment variable is only defined up until the point build command is running.
As soon as build command finishes, these OS environment variables also vanish.

Hi Pankaj,

I think if the firmware module need to show git version information, the version information need to build into firmware binary but not set to OS environment variable.

Thanks

PACKAGES_PATH can include multiple path separated by ";",  looks this patch can't handle such case.
-> I did not know this information, maybe we can enhance this function for handling ";" in PACKAGES_PATH ?
     I would need some time to work on it. I would really appreciate if anybody can help.

Why is this function implemented in build wrapper?
-> The purpose of this patch is to provide a user method to determine which source code was booted?
     Or if a UEFI driver/application has been loaded in system from shell, which was the commit version for that?
     This helps debugging in case we are provided logs of running system or logs of driver/application. 
     Since a user can make a standalone driver/application using build command, I added this function in build wrapper.

Thanks,
Bob

Re: [edk2-devel] [PATCH] BaseTools: Retrieve git version info

Posted by Pankaj Bansal 4 years, 3 months ago

Hi Bob,

You are right. Ideal place for retrieving the git tag/commit info should be a python script.
That way it can be used in all build environments (linux/windows).
Unfortunately I don't have much experience of python programming, which is why I made changes in shell script.
I have made these changes in such a way so as to not impact any exiting functionality and to not cause any build issues.
I thought that applying these changes right now doesn't have any harm.
When someday such changes are put in python script, we can remove these changes from shell script.

Regards,
Pankaj Bansal
